Drive sound with buzzer #70

Open Angel-child opened 4 years ago

Hello again... I enjoy the 15khz change youve done so much! Now my next Question... Is there a way to implement a drive sound also with a buzzer upgrade. I dont find anything about that, so i think its not possible? Best regards Torsten!

There is no buzzer in the mist. But you could hack together a little drive sound code and mix that into the regular audio stream.

Ah ok i thought perhaps a buzzer is upgradeable in the mist on some pins internal... But ists an nice idea with the mixing too

You can connect one to the serial port, but a core should be modified to use it. And what core would benefit from a buzzer without LP filter and sigma-delta DAC? ZX maybe, or Apple II.

Minimig-aga 😁 i meaned it only for the floppy drive sound... in the original minimig Board it was implemented in last core version and a buzzer could be connected to two boardpins optional...So i thought its also possible for the mist

It can also be redirected to the UART pins...but it's not really interesting for me :)
